Letters Patent No. 108,368. dated ilctober 18, 1870.

IMPROVEMENT IN GATES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern.-

Be it known that I, FRANCIS Iavlxcs, ot' East Enterprise, in the county of Switzerland and State of Indiana, have invented au Improved Approach-Gate, and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawing making part of this specification.

Figure 1 being a side view of the gate, closed.

Figure 2 being an enlarged view ofthe toothed segments.

Figure 3 being an enlarged view ot the latching device.

Iligure dheing a plan ofthe gate, open.

Figure 5 being an enlarged view of the bracing device.

Figure (i being a view of the linked rods, enlarged.

Like letters of reference designate correspomling parts iu all the figures.

My invention relates to that class of gates which may be opened or closed by persons without dis` mounting, the entire operation being positive, no dependence being placed on the operation of gravity.

One important feature of' my invention consists in the use ot' a rocking-'bar placed horizontally over the gateway, from post to post, and provided with suitable mechanism and levers for operating the gate.

Another important feature of my invention consists in a peculiar device for releasing thc spring-latch from its catch'.

Another important feature ot my invention consists in the peculiar-torni of toothed segments used, and the operation of the same.

Another important feature ot' my invention consists in the peculiar form of linked rods employed to operate the gate.

Another important feature of my invention consists i'nl the use of a piu and hooks, in lieu ot' notches, for bracing the gate, so as to prevent sagging.

In the drawing- A represents the gate, and B i3 the posts between which it is hung.

Gis a rocking bar, journaled in the said posts at the top, they being ot' suiiicientlength to allow loaded vehicles to pass under. This bar has a piece, c, Vprojecting from its under side, provided with a V-shaped slot, m.. (See lig. 3.) A forked bar, a', passes through guides ou the inner side ofthe outer gate-post, and is provided with a roller, 'f, at the upper end, whichl engages with the slot fm, as shown. A bentspring-- latch, e, is secured to the frogt stile of the gate, which engages with the fork in the lower end ot" the bar d. This constitutes the securing device.

'Ihe rocking-bar is also furnished with a T-shaped piece, b, which projects downward over the hangingsupplementary stile, D. This device is for opening and closing the gate.

'.lhe supplementary stile D is pivoted above and below in the usual manner, and turns in a toothed segment, G, which is secured to the back gate-post. Another segment is secured to the top of the hanging stile E, the two meshing together. Y

The hanging stile has pintles, which are jonrnaled in plates seemed to and projecting from the supplemental-y stile, above and below. These cogged or toothed segments require especial description.

By the use of the said cogged segments,l in the` arrangements shown, the stile E receives an independent rotary motion on its axis, distinct from its motion around the axis ofthe stile D, the latter motion resulting from the-fact that the pintlcs of the stile E are journaled in plates projecting from, and rigidly secured to, the stile I), as before stated. The combined effect produced by the two rotary motions given the stile E is, that when the stile D is rotated through one-fourth oi'a revolution, the stile E makes a quarter revolution on the axis' of the stile D, and an additional quarter revolution ou its own axis, through the operation ci' the cogged segments, which swings the gate open luntil it rests at right angles with the axis of the roadway.

Fig. 6 shows the manner of forming the linked rods by connecting themwith a ring of large size in the middle, and having coupled rings of smaller size at the ends secured to the stile D, and a single ring at the other. 'lhis device is not so liable to become kinked or twisted as'a chain, and is cheaper.

The diagonal bars F F are pivoted to the lower rail ofthe gate, and are provided with a pin, n, (see iig. 5,) at the' other end. Apiece, i, secured to the gate substantially in the manner shown, forms a tongue or guide-piece for the ends of the diagonals, and is furnished with hooks, s s, placed in a row up and down its edge, and projecting obliquely downward. Now, as the gate is loosely jointed, the sag of the front stile may be taken up by lifting it up and inserting the pin a under the proper hook; but when an animal attempts to raise the gate and pass under, the hook beneath the pin catches it and will not allow the gate to bc raised. I claim in this an improvement over simple notches, which have been used for this purpose, as gates so constructed can be raised by animals, and will remain up.

Ifland levers c a, projecting parallel `with the axis of the roadway, are secured to the rocking-bar C.

Operation. f lhe operator pulls down on the handdever a on his side of the gate, which rotates the 'bar C. The first motion is communicated to the forked bar d, through the slotted piece c and roller-pin 7s, and raises the fork iu the bar l (see tine lines iig. 3) clear of the springlatch e. The T-shaped leverb then operates, through the medium ofthe linked rods r/ g, to rotate the stile D. This communicates a rotary velocity to the hanging stile E. rlhe gate swings open and is caught and held by the notched stop-piece H. The rider passes through and pulls down on the other lever. The first mption, owing to the extra width 'of the spaces h h in the segments, now engaged, draws the gate forward a snflicient distance to release the latch from the notch in the stop-piece H, and the gate swings shut.

Having thus described my invention,

That I claim as new, and desire to secure by Letters Patent, is-

1. The rocking-bar C, provided with hand-levers a a, T-piece b, and slotted piece o, when used in the manner substantially as shown and for the purposes set forth.

2. The device-for securing Athe gate to the post when arranged to operate together in the manner substantially as shown, and for the purpose specified.

The toothed segment G G, when arranged to operate in connection with a supplementary stile, D, substantially in the manner as shown and, for the purposes set forth.

4. In combination -with the rocking-bar O and its levers, hanging stile E, linked rods g g,'and segments G G, the supplement-ary stile D, when arranged to operate in the manner Vsubstantially as shown.

Witness my hand this 29th day of Marc-h, 1870.
